T 0 all whom it may concern:

Be it known that I, LOUIS H. LANDRY7 a citizen of the United States, residing a- Uxbridge, in the eounty of W'oroester and State of Massachusetts. have invented a new and useful Loom, or" which the following i a speeitiiation.

This invention relates to a loom suitable for weaving all kinds of fabrics.

The principal objects of the invention are to n'ovide improvements of such a charactenthat the UOUStEUUlLlOll of the 100m will he greatly simplified, and the expense oi manufacturing correspondingly decreased; that the repairs will he nniterislly lessened so that a loo -1 fixer can keep a larger ninnher of looms in repair; that the loom \vill be capable of operating at a higher speed;

that there will be fewer ocoasions on which the loom Will. be stopped and the duration of stopping will be shorter so that the production Will be increased in these Ways in addition to the increase due to the higher speed; and that in the simpler types of looms an attendant can operate a larger numbeiz' An important feature of the invention is the improved pick-out motion'whioh closes and opens the harness Without any vibrating gear and which has means whereby it (1111 be connected in a very sin'lple manner with the loose l'iulley when the inaehine'is stopped. and is provided with a (MD wh wh assists the operator to open the liai-nessos, and than llllit'iillili'lf'llily lots no when they have been entirely opened. This ('21!) he repeated as often as necessary. it is so arranged that it can lie attached to any malte (if loom, and it will close tho'shed each time the lay comes up to the cloth, thus helping; the weaver to pass the broken threads through the harnesses and through. the reed. This is an importantadvantage as herototore; the Weaver has had to level the harnesses each time a thread -was passed through, and this saving in time results in an increase in production.

Another feature of this part of the invention is the reduction in the cost of manufacture and generally in the cost of repairs and the construction thereof in suoh a man-- ner that it Will run at higher speed than heretofore Without slipping ot the harnesses or breakage in the head motion.

The invention also is a yiioahle to an proved ho motion which. will open and close 5 the levers Without the use of vibrator gears, and which is so conneoteol up that it can he caused'to operate it the loose pulley o f the loom through etion shaft when the machine stopped. without ii'iterteri with the shuttle driver or picker.

Fig. 1:8 is a plan show ing a port-ion of the stop motion, and Fi to operate wit out a 1g .1 receive:

mounted. to freely rotate on the driving shaft The power 15 transmitted directly to this driving shaft from tlns loose pulley 'by means of a clutch whicn consists of a as designed to be operated by a swinging' lever 37, link rods 38, and shipper handle 39 or in any other convenient manner. ()11' the driving shaft is mounted a bevel pinion which preferably is driven on to a tapered square endon the shaft so that it will not work loose in operation. This pinion meshes with the driving gear 41. which preferably has removable teeth 4:2. These teeth are preferably made in pairs and. are bolted or otherwise secured removaloly to the base of the gear so that if one or more of them break they can readily be replaced by new ones Without dismounting or replacing the whole gear. 'llhis driving gear is mounted on the crank shaft 43 which operates the machine and which. has links 1 1 connected.

with the lathe for moving it'in the usual way'. A bearing/15 for the crank shaft is provided with. an end bearing fora friction 'shaft This friction shaft is provided with bevel friction disk 17 slidingly keyed thereon. and adapted when pushed backward on the shaft 16 to engage a corresponding friction surface 18 on the rear of the main friction. gear. 'lhe shaft is provided also with a second bevel friction wheel fixed thereon and meshing with a friction surface on the loose pulley and with a friction wheel. on a shaft 53.

When the lever 39' is thrown to force out go 35 to stop the machine it also acts g a link and lever to throw the 'ction wheel 50 into engagement with the cause the shafts 16 and to rotate while the driving shaft is at rest. If while the machine is stop )G(1 it is desired to turn the crank shaft, it is necessary only to turn a small lever or linger (30 which operates friction surface 51 and wheel. 52 which will' instant of time and is of great assistance to the operator in the heavier types of looms it requires considerable force-to push the lathe back. An improved stop motion is also provided which acts in such a way that the loom will stop with the lathe back. This stop motion is shown as comprising a bracket (55 on the breast-beam 66 and a stop motion rocker (37 on the bracket. On the lathe 08 is pivoted a tongue-69 normally held up by the filling thread through connections 7 0. .l Vhen the filling thread breaks these connections and tongue are permitted to drop so that the tongue engages the upper end of the rocker 67 during the next for-.

ward motion of the lathe which operates the lower end to engage an arm 71 on a rock shaft 72. This rock shaft is provided with a spring 73 for holding it in proper position and a dagger 7 1 which is turned'by the above mentioned operation in position to engage a lever 75 which operates the shipper handle 39 and also operates a lever 76 which has connections 77 for operating the lever 62' in a manner which hasbeen de scribed above so as toeause the friction to work and the lathe to heat back. W hen the lathe startsback there is no longer any force acting to hold the wheel 47 against the friction su'rface48. Consequently the lathe will stop at the end of the back stroke.

, N ear the end of the machine he crankshaft 43 has a gear 80 indicatec 1 Fig. 7

meshing with a gear 81'. on a. head motion driving shaft 82. 'This'shaft drives an upright shaft 83 through bevel gears 84. One of the gears 8 1 runs loose on the shaft 83 and is connected therewith by a clutch 85 which is operated by a yoke 86 and a lever 87 adapted to be controlled by a shaft 88 having a handle 89 on the outside of the frame 90 of the machine. A spring 91 normally tends to hold the shaft 88 in. such position that a pin 92 thereof will be in a corresponding depression in a. collar 93 on the shaft so that the handle will turn the shaft. Of course this pin connection or clutch on the handle 89 can be readily disengaged by pulling the handle out and turning it slightly.

The shaft 83 is provided with a bevel gear 100 which .drives a shaft 101 carrying a pair of gears l02-and 103. Located on a stud near. these gears are a'pair of gears 104 and 105. The gears 103 and 104 are constantly in mesh with each other. The gears 102 and 105 are constantly in mesh with a gear 10tl on the chain vylindm shaft 107. ()1! the end of um shaft. .101 is a stud 108 having a key 109 for fixing either of the gears 102 or 103 with rospw-t to the shaft: 101. When the stud is pushed in the gear 102 is fixed to the shaft. and it is loose when the stud is pulled out. The gear 103 is tight when 102 is loose and vice versa,

shaft 101. through the gear 102 and when it is pulled 'out it will be driven indirectly in a reverse direction through the gears 103, 104 and 105. The pulling out of the stud 108 also has another result; that is, it swings a lever 110 which rocks a shaft 111 and turns a roller 112 thereon in position tobe engaged by a cam 113 on a shaft 114 which can be operated manually by a hand wheel 115 to control the piclcout motion.

The spring. 116 is shown for pulling the rod. 111 and roller 112 down. The bottom of'the rod 111 is connected with a lever 117 so that'when the cam 113 pulls up the rod lll'duringa half revolution the opposite end of the lever 117 will be depressed so as to acton an eye 118 and swing down a frame 119 which is pivoted on the frame 90 of the machine until a bevel friction wheel 120 thereon engages with a Wheel 121 fixed to the shaft This causes a shaft 122 on which the wheel 120 is mounted to drive the shaft 83. .The'shaft- 122 is driven through a sprocket chain 123 which is connected with a sprocket wheel 124 on the shaft It will be seen, therefore that by pulling out the stud 108 when the machine is stopped the shaft 107 will be reversed which will reverse the operation of the harnesses as will be described hereinafter and then if the hand wheel 115 is rotated by hand the rotation of.

shaft 114.will he assisted by the power derived from the shaft 1.22 during a half revolution and will not be assisted during gthe other half.

The lever 110 can be swung out from the stud 108 if desired so that the motion can be revenscd by that stud without throwing the power on the shaft 83 from the'shaft 53.

The results to be obtained by these operations will now be described. The shaft 11-1 which has been referred to is provided with bevel gear 130 deriving power, when the machine is running, from a gear 131 on the shaft 83. This shaft 114 in addition to the cam 113 is provided with eccentrics 132 and 133 for opening and closing the shed, re spcctively. Two eccentrics 132 are shown which, as indicated in Figs. land 2, are provided with rod-s 134 connected-with a 1 pivoted frame 135 which has a. cross-bar 136 adapted to engage the several jacks 137 to.

pull them up'into position to close the shed The eccentric133 for opening the shed is conuected by its.rod 140 with an arm 141 projecting from a shed openershaft 142. This shaft is provided with a pair of oppositely extending projections 143 moving in opposite directions as the shaft 142 oseil lates. Pivoted on a rod 144 are center connections 145 each of which is connected with-one of the by a front connecting link 146. Each of these center connections is also pivotally connected with a shed opener finger 147 having two branches provided with teeth 148, one adapted to coope rate with one of the projections 143 and the other with the other. These fingers are located above the chain cylinder shaft 107 on which is mounted a chain cylinder 150. Above the chain cylinder'are indicator levers'151. The rollers comprising the chain 150 are set on the chain cylinder in such manner as may be necessary in order to produce a fabric of the desired weave, then asthe chain cylinder turns these rollers will come under the levers 151 and raise certain of them in each position of the chain cylinder. Those which are raised engage the under sides of the corresponding shed opener fingers and raise them so-thatthe lowerteeth thereof will engage the corre sponding projections 143 while the upper teeth will be raised free of the upper projections. The shed opener fingers which are not so raised will be pushed down by means of a set of spring lingers 152 so that the upper teeth thereof will engage the upper projections 143 and the lower teeth will be "free of the. lower projections. 'Now as the eccentric shaft 114 operates during the connection thereof with the crank shaft through the clutch 85, the shed opener shaft 142 will be oscillated by the eccentric 133 and this will cause the shed to be opened in the appropriate order for producing a fabric of the desired weave, the shed being closed periodically by the eccentrics 132 in the mannerabove described. It is to be ob served (reference being had to Figs. 1 and that the shaft 101 has a cam 155 thercon which at each rotation of that shaft presses outwardly a cam lever 150 on a rock shaft 157. which carries a lock 15h, adapted to en gage a projection 159 on each of thechain operating levers 151 which is not raised by the chain cylinder. This is indicated in Fig. This holds thcinoperative levers down and would prevent the others from coming down on that pick if anything should happen to break or displace one of the chain rollers. A guide 160 is shown for the levers 151 and a, comb 161 for the jacks.

The jacks are shown as comiected-with' the 1 harness 162 in a well known. manner. c

It will be seen that during the operation of the machine from the main crank-shaft 43, the shed will be opened and closed pcriodically in a very simple manner without 3 employing the usual vibrator gears and &

that when the power is shut off from the main crank shaft 43 the auxiliary shaft will still be turning and consequently when the clutch 86 is thrown in, the head motion shaft 83, the eccentric shaft 114, and the shaft 101 can be causedto turn independently of the drive. Thus the harnesses can be operated by power simply by throwing in the clutch handle 89. Moreover, by manipulating'the stud 108 and. turning the hand-wheel 115 the power can be employed while the machine. is not operating to turn the pick-out through half a revolution while during the other half of the revolution it has to be turned by hand. This pick out motion is an important feature because by the operator can tell by the pull of the handwheel when the shed has been closed so that the thread can be passed through and the machine started. Or f he has reversed the 1 drive through the gear 106 and wishes to go back two or three picks, he can do this very readily with no danger of the power carrying the mechanism back too far. The box motion is also driven from the eccentric shaft 114 through an eccentric 165 (see Figs. 7 and 13.) The eccentric rod connected with it operates a link 166 which reciprocates a block 167 to slide in ways 1.68 on the frame. The box'motion is controlled in a way similar to that shown in Figs. 2 and 3 for opening the shed but in this case there is a tilting frame 170 having a pair of hooks 1.71 above and below the block 167 and suiticiently far apart to prevent. both of them engaging the block at the same time. Under the frame 170 or preferably under the lower hook are located a series of operating levers 172 which are controlled by a chain cylinder 173 on the shaft 107. The rotation of the shaft 107 actuates the levers 17 2 through the chain cylinder 173 in the same manner as that described above with reference to the other chain cylinder 150 and causes any one or more of the frames 170 to be tilted up so that their lower hooks engage the block 167 and move with it. The frames 170 are provided with projections 1741 en-' gaging rollers 175 on a corresponding number of bell cranks 176. These bell cranks operate links 177 two of wlnch are supported on pivoted rods 178 and the others on levers 17!) which operate swinging sprocket rw wheels 180. these sprocket wheels engage chains 181 fixed adqustably to the bars 178 and pull the shuttle box up a greater or less distance according to which ones of the frames 170 are moving up. It will be seen thatthe links 177 are shown in Fig. 14 as of two different lengths to provide for four shuttles and four positions of the shuttle box. This can be varied in case a different number of shuttles is employed. A look 186 on the shaft 157 acts to hold the levers 172 like the lock 158. I

In order to stop the loom in case a shuttle is left part way in or part way outof the shuttle box as the latter rises, a feeler is provided on the lathe above the path of the shuttle so that as the shuttle box rises, if a shuttle is under the feeler it will cause the feeler to swing on its pivot against a spring and to turn a lever 202. The end of this lever operates through a system of levers 203 on a finger 204 to turn the shipper lever 30 and stop the loom. This also constitutes a smash protector to stop the picking motions at both ends of the loom in case both shuttles should start to enter the shed at once.

From the description which has. been given, it will be seen that the above mentioned advantages can be secured in a very simple manner, and in such a way that each of the improvements can be applied to practically all types of looms.

While I have illustrated and described a preferred embodiment of the-invention and shown it as applied to a particular type of loom, I am aware that it can be carried out in many other ways and applied to other types of looms without departing from the scope of the invention as expressed in the claims.
